Which countries are included in the international norm?

For BRIGHT, the International norm is based on the national norms (in all N = 15,138):

• Norway (N=2,409)
• Denmark (N=1,007)
• Sweden (N=8,691)
• Finland (N=2,320)
• Mexico (N=711)

The International norm is a weighted average of all the local samples, ensuring equal representativeness for all countries included. National samples are included in the International norm if they have at least 300 responses locally.
